Just had one made to go on my 53' I was switching from an enclosed driveshaft to a S10 T5 with a monte Carlo Rear end. I bought the S10 driveshaft with the T5 $15 and had it shortened and balended, 1 new yoke to match the Monte Rear and ujoints all for $109 they also cleaned the rust up on it and painted it glossy black for me.
Place was Inland Driveline here in KC (I know not much help for you but maybe for someone in my neck of the woods).
